Where to Find the Model Number on a Gas Valve

The model number on a furnace or boiler gas valve is usually on a metal or paper label attached to the valve body. On older valves the label may be dirty, faded, or partly hidden by piping. Getting the full number matters because small suffix differences can indicate different gas type, capacity, opening characteristic, pressure regulation, ignition system, or connection style.
Safety note: Gas valves are combustion safety components. Do not loosen piping, alter regulator settings, or remove a gas valve to read a label unless you are qualified to service gas appliances.
Common label locations
Check these areas with a flashlight:
- Top of the valve body
- Side of the valve facing the burner compartment
- Back side near the manifold
- Near the electrical terminals
- Around the pressure regulator cap
- On a service replacement sticker inside the appliance panel
Honeywell/Resideo-style numbers often look like `VR8200`, `VR8300`, `VR8345`, or similar, followed by letters and digits. The prefix is useful, but the suffix is often what confirms the exact replacement.
Take these photos
For accurate matching, send:
- Full appliance model and serial number
- Gas valve label
- Valve terminals and wiring
- Inlet and outlet pipe orientation
- Manifold connection
- Ignition module or control board label
- Any LP conversion label
Ratings and details that matter
Replacement matching may depend on gas type, voltage, inlet and outlet size, pressure regulator range, ignition type, pilot or direct ignition configuration, slow-opening versus standard-opening behavior, and whether the valve uses specific adapters or flanges.
Resideo installation literature also highlights details such as proper flange O-rings, compatible adapters, leak testing, and using LP-resistant compound for LP installations. Those are installation tasks for a qualified technician, but they show why physical fit is only part of the match.
Need help identifying a valve?
Use the AI HVAC Parts Finder and upload clear photos of the valve label, appliance rating plate, wiring terminals, and gas piping orientation. The tool can help identify the model and look for the correct current replacement.
FAQ
Is `VR8200` enough to order a gas valve?
Usually not. The full suffix and appliance model are needed.
Can a natural gas valve be used for propane?
Only if the specific valve and appliance are approved and properly converted according to manufacturer instructions.
Why does the replacement valve look different?
Manufacturers may supersede older valves with updated models or kits. Compatibility matters more than appearance.
